Not to claim it's the same situation, but there's a difference between things that are officially true and things you should actually respect. You shouldn't respect most of the US judicial system either.
Could you relate that back to your initial claim that "the UK still has an absolute monarchy", which appears to be both officially untrue and untrue in practice?

They don't even make the monarch get a driver's licence or pay taxes.
Maybe they could try writing some of that down in a constitution.
